Welcome to the Predator Ecology Lab!
Since 2008, as part of the Wildlife Science Program in the University of Washington's School of Environmental and Forest Sciences, we have sought a better understanding of how predators influence their surroundings by interacting with one another and their prey. Much of our work also seeks solutions to the challenges of large carnivore conservation and management in a changing world.

November 15, 2018: Here in the PEL, we strive to maximize the reach of our research. To that end, Lauren Satterfield has truly distinguished herself of late. Namely, she has given no less than six public talks or workshops over the past couple of months. Lauren's audiences have included the Friends of the Little Pend Oreille National Wildlife Refuge, the Alderleaf Wilderness College, Seattle City Light, and the Methow Conservancy. For more details, please see the Washington Predator-Prey Project website. Thank you, Lauren, for helping to broaden our impacts!
October 24, 2018: We have a flurry of recent talks to report! First, on October 10, Clint Robins delivered a talk titled, "Investigating the effects of urbanization on cougar foraging ecology along the wildland-urban gradient of western Washington" as part of a symposium titled, "Carnivore Ecology in the Built Environment" at the 25th Annual Meting of The Wildlife Society in Cleveland, OH. A bit later, on the 12th, Lauren Satterfield presented a talk titled, "Competition on two legs and four: impacts of wolf-cougar occurrence one source selection and survival across an anthropogenic gradient" as part of the International Wolf Symposium in Minneapolis, MN. Not to be outdone, Lily Van Eeden presented a talk titled, "Applying lessons from wolf management to an Australian canid: the
importance of people" as part of a special symposium titled, "Challenges of Balancing Stakeholder Engagement and Scientific Decision-Making to Inform Wildlife Policy" at the TWS conference and then again at the International Wolf Symposium. She also presented a poster titled, "Social identity and perception of animal "nativeness" shape public attitudes towards wildlife management" at the former meeting. Hearty congratulations to all of the presenters!

June 14, 2018: We have a new paper out in Conservation Letters, led by PEL collaborator Dan Thornton (of Washington State University), titled, "Asymmetric cross-border protection of peripheral transboundary species". Made possible by a Catalyzing New International Collaborations (CNIC) grant from the National Science Foundation, the paper highlights the inadequate conservation attention that is currently being given to North American species (mammals, birds, and herpetofauna) whose ranges span the borders of USA-Canada or USA-Mexico. Thanks, Dan, for inviting us to be a part of this exciting effort, and to all of the co-authors who made the workshop on which the paper is based such fun!

March 9, 2018: More exciting news to report! Today, Justin Dellinger successfully defended his dissertation titled, "Impact of re-colonizing gray wolves on mule deer and white-tailed deer in north-central Washington". Justin's project was the first of three focused on the ecological consequences of wolf recolonization for prey and plant communities in eastern Washington, and he did a super job of kicking things off. Now, he gets to return to northern California, where is working for the California Department of Fish and Wildlife as a senior environmental scientist. Congratulations, Justin, and thank you for all of your hard work! We are also grateful to Matt Vanderhaegen of WDFW and Eric Krausz and Donovan Antoine of the Colville Tribes for making the long trek to attend the defense!
March 1, 2018: Another achievement to report. Today, Laurel Peelle successfully passed her PhD qualifying exam and did so with distinction. Now, Laurel moves on to preparing for her general exam (proposal defense). In the meantime, she has earned some well deserved rest. Congratulations, Laurel, and thanks also to committee member Ben Maletzke for making the long drive over from Cle Elum to join us!
February 22, 2018: Kudos to Carolyn Shores, who while heading down the home stretch on her dissertation just assumed a new position as an Ungulate Landscape Ecologist with the Ministry of Forests, Lands, Natural Resource Operations, and Rural Development in Willliams Lake, BC, Canada! Among many other tasks, Carolyn will be focusing on the ecology and management of woodland caribou. Best of luck, Carolyn!
